Analyzing Temporal Morphometric Changes In River Nile's Forced Bends Via Rs/Gis Methods: A Case Study Of The Damietta Branch In Egypt, Reham Abdel-Bar Aborahma, Ibrahim Rashwa, Asaad Matter Armanuos

Journal of Engineering Research

River Nile, among the world's longest rivers, features the crucial Damietta branch in Egypt, serving as a vital irrigation source and navigation pathway from Cairo to the Mediterranean Sea. Post the Aswan High Dam's construction, significant morphological shifts occurred in this branch, particularly impacting sedimentation and erosive patterns, notably at river bends. This study investigates the long-term morphometric evolution of six forced bends along the Damietta branch of the Nile River from 1987 to 2015 using remote sensing (RS) and geographic information system (GIS) techniques. Three image classification methods—onscreen digitizing, maximum likelihood classification, and histogram thresholding—were compared for shoreline delineation …

Design And Performance Analysis Of A Frequency-Reconfigurable Rectangular Patch Antenna With Dual-Slot Defected Ground Structure For Gsm Band, Sara Abdelbaset, Ashraf Khalaf, Amr Hussien, Ahmed A. Kabeel

Journal of Engineering Research

In this paper, an innovative frequency-tunable rectangular patch antenna is presented, featuring interlaced circular and U-shaped narrow slots, combined with a rectangular-shaped defected ground structure (DGS).

The Effects Of Recent Modifications In Egyptian Building Regulations On Urban Development And Socioeconomic Conditions Over The Past Decade, Mohamed M. Abohelal

Journal of Engineering Research

Over the past decade, Egypt has witnessed significant transformations in its urban regulatory framework, particularly through successive amendments to the Unified Building Law No. 119 of 2008. These legislative changes, implemented in 2015, 2021, and 2024, reflect evolving state strategies to manage urban growth, streamline construction processes, and address challenges in regulatory compliance. The 2015 amendments sought to enhance administrative coordination and facilitate permit acquisition, while the 2021 reforms imposed stringent restrictions on building height, coverage ratios, and facade dimensions, provoking widespread controversy due to their misalignment with local urban realities and economic capacities. In response to ensuing public and …

Morphological Changes Downstream Beni-Suef Bridge On The Nile River In Egypt, Muhammad Ahmad Abdul-Muttalib, Ahmed Moustafa Moussa, Gamal Helmy Elsaeed, Suzan Ahmed Mohammed

Journal of Engineering Research

The construction of the Beni-Suef bridge, spanning 550 meters over the Nile River, resulted in sediment accumulation and hindered navigation. This study investigates the causes of the morphodynamic changes and explores the impact of dredging as a mitigation measure through the area which extended approximately 2.6 kilometers downstream the bridge. A one-dimensional numerical model (HEC-RAS) was employed, utilizing bathymetric surveyed cross-sections from 1982, 2002, and 2004, along with discharge data from downstream Assuit Barrage and water levels from upstream Delta Barrage as boundary inputs. The model was calibrated and validated using measured water and bed levels. Sediment properties and bed …

Assessment Of Safety Monitoring Indexes Of High Rcc Gravity Dams Considering Hydraulic Fracture, Mohamed Ramdan, Jinsheng Jia Professor, Xu Li Professor

Journal of Engineering Research

High concrete gravity dams, particularly Roller-Compacted Concrete (RCC) types, face long-term safety challenges due to weak interlayer formation and crack propagation. This study presents a comprehensive evaluation of safety monitoring indexes for the Guxian high RCC dam (currently under construction in China) using both numerical and theoretical models. A Finite Element Method (FEM) was applied with two approaches: the strength reduction method, which considers weak layers, and the overloading method, which simulates extreme loading without accounting for material degradation. A comparative analysis between these two methods was conducted to determine which more effectively evaluates dam safety under varying conditions. Additionally, …

The Role Of Artificial Intelligence In Promoting Diversity And Inclusion In Urban Public Spaces Aspects Contributing To Mental Health Preservation, Rania B. Shokry

Journal of Engineering Research

I.

Cities are complex systems shaped not only by infrastructure but also by the emotional, sensory, and socio-political experiences of their inhabitants. Despite this multidimensional nature, urban planning is often guided by conventional frameworks that overlook the lived realities of residents. As critical components of the urban fabric, public spaces play a significant role in shaping social identity, cohesion, and psychological well-being.

This research explores the transformative potential of Artificial Intelligence (AI) in enhancing diversity and inclusion within urban public spaces, with a particular focus on its impact on mental health. Social segregation remains a major barrier to inclusive urbanism; …

Aphasia In South Asian Languages (Asal) Project: A Protocol Of Connected Speech Tasks For Investigating Cross-Linguistic Grammatical Profiles In Aphasia For South Asian Languages, Arpita Bose, Sakshi Bhatia, Lakshmi Venkatesh, Sayantani Banerjee, Gurujegan Murugesan, Sunila John, Sakshi Upadhyay, Manaswita Dutta, Mythili Menon, Danielle Fahey, Multiple Additional Authors

Speech and Hearing Sciences Faculty Publications and Presentations

Background

Languages vary in their syntactic (e.g. word order in sentences), lexical (e.g. presence of specific word classes), and morphological (e.g. inflectional or derivational forms of words) properties. This cross-linguistic variation in language typology influences the manifestation of agrammatic symptoms. However, most theoretical models of agrammatism are based on English and a few European languages, limiting their generalizability. This narrow focus neglects the rich syntactic, lexical and morphological variations available in languages globally. Clinically, the lack of language-specific characteristics of agrammatic impairments limits translational potential for precise and improved diagnosis. The Aphasia in South Asian Languages (ASAL) project addresses this …

Introduction To Special Issue On Unjust “Permission Structures” In/As Technical Communication, R. J. Lambert, Randall W. Monty, Kymberly O. Morquecho, Sarah Warren-Riley

Writing and Language Studies Faculty Publications

The term “permission structure” has been popularized to describe a specific rhetorical strategy whereby communicators use the audience's existing beliefs and values to persuade them to change their original positions and/or take actions they otherwise would not. Even in its popular uses, permission structuring may be usefully understood as a form of technical communication by which audiences are strategically persuaded to accept or reject complex policy, scientific, and legal topics. However, scholars must resist popular jargon outpacing and superseding the use of technical concepts and critical discourse. Taken together, the seven articles in this special issue potentiate multiple critical, pedagogical, …

The Spread Of China’S Cultural Soft Power Through The Chinese New Year Festival In Pontianak, Kevin Thedeus, Nuraeni Nuraeni

Global: Jurnal Politik Internasional

Chinese New Year (CNY) celebration is one of the biggest celebrations for the Chinese Indonesians in Pontianak. This celebration allows the Chinese ethnic groups to remember and maintain their traditional roots while living in the host country. However, the high interest from non-Chinese Indonesians in visiting and participating in the CNY celebration raises questions about whether this diasporic activity unintentionally strengthens the favourability of the Indonesian people towards China and is used as a means of China's soft power. This study will discuss the spread of culture from the CNY Festival in Pontianak, which can serve as an instrument of …

The Political Framing Of The 2024 China-Indonesia Joint Statement, Mahbi Maulaya

Global: Jurnal Politik Internasional

Political leaders always carefully choose what to say and how to state it, as all words count for influencing the public, explicitly or implicitly. Eventually, the ideas framed in a political statement are best understood contextually rather than merely textually. After Prabowo Subianto, the president of Indonesia, visited China in November 2024, both countries released a controversial joint statement. This article aims to analyse the political frames observable in the 2024 China-Indonesia joint statement with a discourse analysis method. The article found five political frames in the statement: 1) Indonesia agrees to China’s vision of global order; 2) China has …
